Introduction to Remote Sensing

What is Remote Sensing?

Remote sensing is used to obtain information about objects.
Data is collected with an instrument an then analysed. The instrument used is not in direct contact
with the object. The platforms used are located "at a distance" from the earth’s surface (for example,
aircraft and satellites). These carry sensors to observe and study the earth, its land surface, the oceans,
the atmosphere and the earth's dynamics from space
(ESA Eduspace).
